The severity of acute upper gastrointestinal bleeding depends mainly on the etiology and the promptness of treatment. Regardless of the cause of gastrointestinal bleeding, if the treatment is timely, the prognosis is different depending on the cause. Some patients can be cured, for example, acute upper gastrointestinal bleeding caused by peptic ulcer can be cured by medication and hemostatic treatment, and such patients do not affect their life expectancy and can survive for a long time. In some patients, although the gastrointestinal bleeding can be stabilized for a short period of time, the cause of the disease cannot be removed and recurrent gastrointestinal bleeding will occur. If the gastrointestinal bleeding is not treated in time, or if the bleeding is not stopped and shock occurs, the patient may die at any time. The situation is more serious in this type of patients, and it is common to see bleeding caused by esophagogastric fundic varices.
